2011-08-29mount.cifs: fix the conflict between rwpidforward and rw mount optionsPavel Shilovsky1-1/+1
Both these options are started with "rw" - that's why the first one isn't switched on even if it is specified. Fix this by adding a length check for "rw" option check. Signed-off-by: Pavel Shilovsky <piastry@etersoft.ru>
2011-08-25autoconf: work around broken wbclient.h fileJeff Layton1-27/+32
Some versions of wbclient.h have function declarations with bool type args, but they don't include stdbool.h themselves. Make sure that we can deal with that by telling the autoconf test to include stdbool.h explicitly. In order to do that properly we need to move some of the standard header and type tests up in the file. Signed-off-by: Jeff Layton <jlayton@samba.org>

2011-08-25cifsacl: Add configure and make directives for cifsacl (try #2)Shirish Pargaonkar3-4/+53
Add configure directives for option cifsacl. The default action is to enable cifsacl option. cifsacl option is enabled or disabled in a similar way to cifs.idmap in the same function. In addition, for cifsacl, check for sys/xattr.h is done in the smae .m4 file. Add directives to build getcifsacl in Makefile. Signed-off-by: Shirish Pargaonkar <shirishpargaonkar@gmail.com>

2011-07-19cifs-utils: add a note about inclusion of keys.dns_resolver program in keyutilsJeff Layton1-2/+5
As of version 1.5, the keyutils package is shipping a generic dns_resolver upcall. Add a note to the cifs.upcall manpage that mentions this and recommends the use of that program over cifs.upcall. Eventually, we may want to be able to conditionally compile out the dns_resolver part of the upcall, but it's already pretty small and wouldn't save us very much.

2011-07-12mtab: handle ENOSPC/EFBIG condition properly when altering mtabJeff Layton3-2/+53
It's possible that when mount.cifs goes to append the mtab that there won't be enough space to do so, and the mntent won't be appended to the file in its entirety. Add a my_endmntent routine that will fflush and then fsync the FILE if that succeeds. If either fails then it will truncate the file back to its provided size. It will then call endmntent unconditionally. Have add_mtab call fstat on the opened mtab file in order to get the size of the file before it has been appended. Assuming that that succeeds, use my_endmntent to ensure that the file is not corrupted before closing it. It's possible that we'll have a small race window where the mtab is incorrect, but it should be quickly corrected. This was reported some time ago as CVE-2011-1678: http://openwall.com/lists/oss-security/2011/03/04/9 ...and it seems to fix the reproducer that I was able to come up with.

2011-05-24cifs-utils: Create new binary cifs.idmap for sid to uid/gid mapping (try #4)Shirish Pargaonkar4-3/+266
Handle cifs.idmap type of key. Extract a SID string from the description and map it to either an uid or gid using winbind APIs. If that fails (e.g. because winbind is not installed/running or winbind returns an error), kernel assigns uid and gid (from mount superblock). Enable including winbind header files and idmapping code conditional to winbind devel rpms (header and library). An entry such as this create cifs.idmap * * /usr/sbin/cifs.idmap %k is needed in the file /etc/request-key.conf.

It currently test to see if errno == -EINVAL and whether the endptr is '\0'. That's not correct however. What we really want it to do is check to see if any error occurred by setting errno to 0 before the conversion. If one did, then try to treat the value as a name.

We get a pointer to the end of the address string (ipaddr), but the call snprintf and pass in tmpbuf which is a pointer to the beginning of the address string. If someone passes in an address with a scopeid then we end up overwriting the entire address string. Reported-by: Björn JACKE <bj@sernet.de> Signed-off-by: Jeff Layton <jlayton@samba.org>
2011-02-08mount.cifs: reacquire CAP_DAC_READ_SEARCH before calling mount(2)Jeff Layton1-2/+8
It's possible that the user is trying to mount onto a directory to which he doesn't have execute perms. If that's the case then the mount will currently fail. Fix this by reenabling CAP_DAC_READ_SEARCH before calling mount(2). That will ensure that the kernel's permissions check for this is bypassed.

2011-01-31mount.cifs: don't try to alter mtab if it's a symlinkJeff Layton3-1/+18
Some distros replace /etc/mtab with a symlink to /proc/mounts. In that situation, mount.cifs will hang for a while trying to lock the mtab. /bin/mount checks to see if the mtab is a symlink. If it is or if a stat() call on it fails, it doesn't try to to update the mtab. Have mount.cifs do the same. Signed-off-by: Jeff Layton <jlayton@samba.org>
